+# ./hack/patch/cherrypick.sh
+
+Handles cherry-picks of PR(s) from etcd master to a stable etcd release branch automatically.
+
+## Setup
+
+Set the `UPSTREAM_REMOTE` and `FORK_REMOTE` environment variables.
+`UPSTREAM_REMOTE` should be set to git remote name of `github.com/coreos/etcd`,
+and `FORK_REMOTE` should be set to the git remote name of the forked etcd
+repo (`github.com/${github-username}/etcd`). Use `git remotes -v` to
+look up the git remote names. If etcd has not been forked, create
+one on github.com and register it locally with `git remote add ...`.
+
+
+```
+export UPSTREAM_REMOTE=origin
+export FORK_REMOTE=${github-username}
+export GITHUB_USER=${github-username}
+```
+
+Next, install hub from https://github.com/github/hub
+
+## Usage
+
+To cherry pick PR 12345 onto release-3.2 and propose is as a PR, run:
+
+```sh
+./hack/patch/cherrypick.sh ${UPSTREAM_REMOTE}/release-3.2 12345
+```
+
+To cherry pick 12345 then 56789 and propose them togther as a single PR, run:
+
+```
+./hack/patch/cherrypick.sh ${UPSTREAM_REMOTE}/release-3.2 12345 56789
